As the information-oriented society makes progress, the role of Image has much influence on human being in space as a medium for information delivery and a means of artistic communication. These influences are appeared as expressional characteristics of the image such as the reproducibility of reality and unreality in the real world, the synchrony of expression of time, visual formality, a sign and the transmission of moaning. For these, the investigator examined the meaning of image in aspace, taking into consideration of the interrelationship of image, space, and human being. As study findings show, the expressional characteristics of image in space have such visual effects as a space in which pictorial formality and object exists, in which the mutual understanding of communication exists, and that realizes immaterial membrane in the aspect of time and space, according to the electronic light, color, and formation of the image media. In addition, it become clear that the characteristic could be staged on various circumstances by constructing the relationship between an object and a point of time interactively with bidirectional communication through combining technology and art. This suggests that the image develops as the form of sensory communication via interacting of space and human being.

이 논문에서는 시각적으로 명암이 인간의 정서에 영향을 미친다는 그레이브스의 명암이론을 적용하여 "라이온 킹" 에서 사용된 명암의 유형을 분석하고 작품 내에서 시각적으로 표현된 명암이 내러티브에서 전개되는 정서의 흐름과 어떠한 관계를 맺고 있는지에 대한 유형을 분석하였다. 이를 통하여 명암이 시각이미지에 끼치는 영향과 더불어 정서적인 분위기 표현에 중요한 요소로 작용한다는 점을 규명하고자 하였다. 애니메이션에서는 실사 영화와는 달리 내러티브상에서 전개되는 캐릭터들의 정서적 변화에 따른 이미지 연출이 더욱 강조 된다. 이는 관객들의 감정이입을 강화시키는 중요한 수단이 된다.

The paper brings to question how image as a medium is becoming a replacement for traditional letters in the modern culture. Reflection the importance of image in the context of modern society with the changes in the values of communication. The importance of letters in its traditional format as a book that signified not only the method of communication but also power for those who governed during the days of illiteracy in the past has changed, in the beginning with the development of printing and today with movies etc. that supply endless images instead of words as a means of communication. The images are the next generation in the method of communication and can be noted from the earliest civilizations such as Egypt where the method of communication was not words but drawings that depicted specific significations. The use of images for communication purposes in light of this fact suggests that images was being used before words in societies and its communicative values greater than that of words.

Purpose: This study aims to develop new markers based on silicone rubber and urethane rubber to enhance visibility in low magnetic field magnetic resonance (MR) imaging. Methods: Four types of markers were fabricated using two different base materials. Two of the markers were composed of two different types of silicone rubber: DragonSkin™ 10 MEDIUM and BodyDouble™ SILK. The other two markers were composed of types of urethane rubber: PMC™ 780 DRY and VytaFlex™ 20. Silicone oil (KF-96 1000cs) was added to the fabricated markers. The allocated amount of oil was 20% of the weight (wt%) of each respective marker. The MR images of the markers, with and without the silicone oil, were acquired using MRIdian with a low magnetic field of 0.35 T. The signal intensities of each MR image for the markers were analyzed using ImageJ software and the visibility for each was compared. Results: The highest signal intensity was observed in VytaFlex™ 20 (279.67±3.57). Large differences in the signal intensities (e.g., 627% in relative difference between BodyDouble™ SILK and VytaFlex™ 20) among the markers were observed. However, the maximum difference between the signal intensities of the markers with the silicone oil showed only a 62% relative difference between PMC™ 780 DRY and DragonSkin™ 10 MEDIUM. An increase in the signal intensity of the markers with the silicone oil was observed in all markers. Conclusions: New markers were successfully fabricated. Among the markers, DragonSkin™ 10 MEDIUM with silicone oil showed the highest MR signal intensity.

Most existing low-light enhancement algorithms either use a large number of training parameters or lack generalization to real-world scenarios. This paper presents a novel lightweight and robust pixel-wise polynomial approximation-based deep network for low-light image enhancement. For mapping the low-light image to the enhanced image, pixel-wise higher-order polynomials are employed. A deep convolution network is used to estimate the coefficients of these higher-order polynomials. The proposed network uses multiple branches to estimate pixel values based on different receptive fields. With a smaller receptive field, the first branch enhanced local features, the second and third branches focused on medium-level features, and the last branch enhanced global features. The low-light image is downsampled by the factor of 2b-1 (b is the branch number) and fed as input to each branch. After combining the outputs of each branch, the final enhanced image is obtained. A comprehensive evaluation of our proposed network on six publicly available no-reference test datasets shows that it outperforms state-of-the-art methods on both quantitative and qualitative measures.

The spraying status of the electrostatic sprayer was evaluated by processing surface spraying images of the natural leaves. Water solution of the fluorescent material was used as a spray medium. The image of the lights reflected by fluorescent droplets was captured under UV light using a color CCD camera. Coverage rate, particle density, and the size distribution of particles were analyzed from the surface images of leaves under various spraying conditions such as spraying nozzle angle and object distance. Spraying characteristics of the electrostatic sprayer was evaluated in comparison with the conventional one. In a case of electrostatic sprayer, coverage rate and particle density increased by the average of 1.57times and 1.01times respectively under various nozzle angles and distances. The number of particle under the diameter of 50 ${\mu}{\textrm}{m}$ also increased significantly.

Carbon electrode was applied to a wastewater treatment system as biofilm media. The spatial distribution of heterotrophic bacteria in aerobic wastewater biofilm grown on carbon electrode was investigated by scanning electron microscopy, atomic force microscopy, and biomass measurement. Five volts of electric oxidation and reduction potential were charged to the carbon anode and cathode of the bioelectrochemical system, respectively, but were not charged to electrodes of a conventional system. To correlate the biofilm architecture of bacterial populations with their activity, the bacterial treatment efficiency of organic carbons was measured in the bioelectrochemical system and compared with that in the conventional system. In the SEM image, the biofilm on the anodic medium of the bioelectrochemical system looked intact and active; however, that on the carbon medium of the conventional system appeared to be shrinking or damaging. In the AFM image, the thickness of biofilm formed on the carbon medium was about two times of those on the anodic medium. The bacterial treatment efficiency of organic carbons in the bioelectrochemical system was about 1.5 times higher than that in the conventional system. Some denitrifying bacteria can metabolically oxidize $H_{2}$, coupled to reduction of $NO_{3}^{-}\;to\;N_{2}$. $H_{2}$ was produced from the cathode in the bioelectrochemical system by electrolysis of water but was not so in the conventional system. The denitrification efficiency was less than $22\%$ in the conventional system and more than $77\%$ in the bioelectrochemical system. From these results, we found that the electrochemical coupling reactions between aerobic and anaerobic reactors may be a useful tool for improvement of wastewater treatment and denitrification efficiency, without special manipulations such as bacterial growth condition control, C/N ratio (the ratio of carbon to nitrogen) control, MLSS returning, or biofilm refreshing.

The purpose of this study was to investigate the effect of perceiver's social value, hair style, and hair color of object person on image perceptions. For social value variable, materialism and traditionalism were investigated. Subjects were 343 women in Seoul. Perceiver's materialism gave a significant influence on perception of elegance. The less materialistic group evaluated the hair style of object person more elegant than the more materialistic group. The more traditional group evaluated bright brown hairs less pretty than the less traditional group. This means that traditional people have less preferable image on bright brown hairs compared to the black and dark brown hair as it is different from Korean traditional hair color. Medium straight hair styles were evaluated lowest in preference and individuality. Short straight hairs were evaluated as the most elegant style and medium permanent hairs as the least elegant one. Long wavy hairs were evaluated highest in femininity, and straight hairs were evaluated lower in prettiness and activity than wavy hairs. The bright brown hairs were evaluated as the most individual color, and black was the least one. The bright brown was perceived lowest in elegance. Black and dark brown of the short straight hair style were perceived much more elegant than the bright brown of the same style, and black long wavy hairs were evaluated highest in femininity. The present findings provide that social value, hair style, and hair color are significant characteristics when perceiving women's image.
